The Nanu

The Nanu is our go-everywhere day bag. It's as at home on the commute to work as it is in the mountains.

A stiff sewn-in foam back panel gives great support and shape to the pack at any volume. This means that whether you are just taking your computer and some lunch or you're headed to the beach and have stuffed the bag to bursting, it still carries well.

The laptop sleeve is padded with thin 3mm foam, holds the laptop 10cm above the bottom of the backpack and can fit up to 16" laptops.

Whilst weight wasn't our priority when designing this sack, it's still pretty lightweight at around 570g / 20.1 oz.

Features

G Hook for Top Strap

A webbing top strap secured with a metal G hook instead of a buckle.

Roll Top Zip Pocket

An easily accessed zippered pocket above the shoulder straps that can fit those keep close items. Easily fits a phone, keys, passport or notebook.

Removable Padded Back Panel

Uses shaped 8mm closed cell foam. Can be removed when the pack is empty for a 25g weight reduction.

Snap Fasteners

These fasteners help secure the roll top and ensure it remains closed while rolling down and compressing.

Haul Loop

This simple webbing loop is there so you can pick up and set down your pack without putting excess strain on the shoulder straps. Using this will extend the life of your backpack and keep your shoulder straps in good condition.

S-Shaped Shoulder Straps

Our S-shaped straps are designed to perfectly hug the contours of your body.

Sewn using 11mm foam, durable 210d Robic Extreema face fabric and breathable and soft 3mm thick spacer mesh.

Whistle Sternum Strap

Elasticated, removable and height adjustable, on a long thru hike we recommend keeping it with the whistle facing down to prevent it getting blocked.

Roll Top Closure

The closure has a 15mm vertical side compression. The roll top can also be clipped together at the top (dry bag style) and the side compression clipped around the front of the bag to aid carrying snowshoes or maybe a huge packs of chips etc.

Dyneema Stretch Front Pocket

Made with Dyneema stretch fabric. Can hold 5L, not included in the total volume.

Shoulder Pocket

Each pocket is super stretchy and big enough to hold most smartphones, a day’s worth of snacks or a 700ml water bottle. The elastic is fixed and, owing to its clever design, does not need a tensioner.

Bottom Pocket

Easy-access bottom pocket featuring a large opening on the wearer's right and trash port on the wearers left. The bottom pocket on the Nanu also features a webbing loop for attaching a bike light.

Sewn using Dyneema stretch fabric.

Single Top Strap

A simple adjustable webbing loop to help close the pack or secure a large light item like a roll mat.

Padded Laptop Sleeve

The Laptop sleeve on the Nanu features a 3mm thick foam pad that protects the laptop from the backpack contents. The sleeve holds the contents 10cm above the base of the bag which offers some protection from rough handling and drops.

The Nanu FAQ

Does my torso size affect the volume?

No, In all of our backpacks the height remains the same regardless of torso size.

So a large torso pack will have the exact same volume as a small torso pack.

What does recomended load capacity mean?

This is our best guess at what the average person could load into this pack while still being comfortable.

This is entirely dependant on your physiology so must be taken with a pinch of salt. i.e. If you are Chris Hemsworth (Thor... Phwoar!), you may well be able to carry more weight than, say, Gollum from the Lord of the Rings.

In general, we find our limits to be fairly accurate, however, If you find yourself nearing or exceeding the number listed with any regularity, then you should probably look at a more supportive pack from our range.

Are Atom Packs backpacks waterproof?

Our packs are not waterproof.

We use highly waterproof fabrics but we do not tape the seams. Therefore some water may ingress into the pack during periods of extended rain.

Do I need to use a pack liner?

Yes, even though our materials are water resistant, the seams are not taped and thus water may ingress into the pack during extended rain.

Any items that you wish to keep dry must be kept in a waterproof stuff sack or liner.

What size laptop fits in The Nanu?

The Laptop Sleeve can accommodate laptops up to 16" wide with space for a sleeve or case. a 17" laptop fits in without a case.

Fantastic quality and workmanship, as you’d expect from Atom Packs.

Just awesome.

Wanted to get some good use out of the pack before writing a review. I've been using it as my daily carry for the last 9 months and have been super happy with how it's performing.
First thing, is just how light the bag is given how robust the materials and construction are.
Next, the pack can actually fit more than you might think. Some strategic placement along with the flexibility of the fold top means you can cram a lot in.
There isn't a whole lot of pockets and organisation options but I think that's a good thing. Just helps you steam line what you really need and you learn to economise.
For my use, it's very comfortable - some might prefer thicker shoulder padding but it's not necessary given what the pack was designed for.
Finally, the thing I appreciate the most is just how tough and well put together is. You know it will keep going for a very long time and I'm liking how the material is breaking in and fading nicely with the Storm Grey option.
Super stoked and thanks for building such a workhorse!

A brilliant bag

I’ve owned my Nanu for about 6 months. I use it as a work bag, on short work trips and shopping and out walking. It’s great at all of these things. It’s super light, comfortable, capacious and well made. One big surprise is how great is it is for one bag travel on planes. The stuffable external pockets are great to quickly throw belts etc in when going through security and it sits nicely under the seat in front. Minor gripes: the sternum strap buckle is fiddly and a little more stiffness where the closing strap connects near the top pocket might make using the top pocket a little easier at times. I love the bag and would highly recommend it.

A little gem of a pack!

I bought the Nanu with the idea of maybe using it here and there when I used public transport or my bike to head into work however this didn't exactly go to plan, my better half (Mona) and I are in training for the T.M.B in June and have been hiking 25-30k at the weekends in preparation I have been using my Talon 33 loaded with around 7-9kg, after receiving the Nanu and wearing it I thought hmmm maybe I can use this in place of the Talon so the following weekend I loaded up my Nanu with around 7kg and off we went....all I can say is wow! It's so comfortable I'm impressed so much with this pack I use it every day for something now wether it's walking the dogs, going to the gym, nipping down to the shop for a few groceries it literally goes everywhere with me and I don't even notice it's there, even when I loaded up with 9.7kg one weekend it was still really comfortable over 22k over rough terrain.
This is a fantastic little pack and I'm over the moon with my purchase. Thanks Tom and team keep up the great work👍🏻

Great pack! Nanu X25 in mountain brown

I'll be taking this pack on a two-week trip to England (Midlands and South East) in the summer. It's just barely holds everything I need without stuffing. Have taken it on one winter weekend trip and was great for that as well. Small and light enough that I can empty it out and use it as a day bag when I get where I'm going.
